Motor starter module

Abstract

A motor starter module is provided, the module according to the present disclosure including a PCB (Printed Circuit Board) substrate configured to communicate with and control the magnetic contactor, a mechanism part operating in association with an operation of the magnetic contactor, and an upper case covering the PCB substrate and an outer case of the mechanism part, whereby the magnetic contactor can be locally and directly driven, and controlled via communication to reduce a line cost, to shorten an operation time and to promote maximization of spatial utilization.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]Pursuant to 35 U.S.C.§119 (a), this application claims the benefit of earlier filing date and right of priority to Korean Patent Application No.10-2011-0134363 filed on Dec. 14, 2011, the contents of which are hereby incorporated by reference in their entirety.BACKGROUND OF THE DISCLOSURE[0002]1. Field of the Disclosure[0003]The present disclosure relates to a motor starter module, and more particularly to a motor starter module configured to reduce a line cost, to shorten an operation time and to promote maximization of space utilization by locally and directly driving a magnetic contactor and controlling the magnetic contactor via communication.[0004]2. Discussion of the Related Art[0005]Generally, a motor starter includes a manual motor starter (MMS) and a magnetic contactor (MC). In general, the motor protection circuit breaker, so-called a ‘manual motor starter’ (so called MMS as abbreviated), a device used for an electric line of ra...

AI Technical Summary

Benefits of technology

The present disclosure provides a motor starter module that solves problems of spatial restriction and cost increase without adding extra materials or wiring works. The module allows for direct and local driving of the magnetic contactor, reducing line costs and operation time. The module maximizes spatial utilization and promotes efficiency.

Problems solved by technology

Thus, in a case there occurs a defect on the PLC (10) failing to monitor the status of the magnetic contactor, the control of ON / OFF of the magnetic contactor becomes disabled to cause a fatal damage to the system.

Furthermore, in a case a conventional motor starter is used, an auxiliary relay or an I / O terminal is separately required for additional functions, and an additional material or a wiring work is required to increase a manufacturing cost and to create a spatial restriction.

Naturally, this results in additional costs over time.
